At 9:30 p.m. PST, a Netflix spokesman said the issue affects “some, but not all devices that can stream from Netflix. Our teams are working hard with Amazon Web Services to address the issue and hope to have streaming available for everyone again soon.”

An Amazon (Nasdaq:AMZN) spokeswoman confirmed Monday night that the company was still working to resolve the problems.

Amazon Web Service operates server systems that deliver Internet service for many companies. It has been hit by several outages this year, knocking out websites such as Pinterest, Instagram and Foursquare.

Netflix's cloud architect, Adrian Cockcroft, said not all customer devices were affected by the outage, The Wall Street Journal reported.

"Some devices working, others not," he said on his Twitter account. "Still waiting for AWS to fix it."
